Good morning/afternoon/evening everyone! @hannakin__ here bringing you the evening session from the aquatics centre. There are some absolutely massive races lined up tonight with all the big stars in action.

The BBC have the brilliant Bert Le Clos in the studio, can his son pull off a second consecutive victory over Michael Phelps in the 200m Butterfly Final tonight?

First up it's the Men's 100m Freestyle Semi Finals. Here's your line up for the first SF:

This should be a very interesting SF, World Champion Ning Zetao and defending Olympic Champion Nathan Adrian are in the outside lanes, with Aussie favourite Cam McEvoy in the middle.

They're off and it's the Russian Morozov at the turn

Nathan Adrian comes in first with McEvoy in second and the American Caeleb Dressel in third. Ning Zetao way down in 6th, not sure that'll be good enough for the final.

Onto the second SF, we've got British interest in the form of Duncan Scott in this one. Here's the line-up:

Canada's Santo Condorelli out in lane 3, but before he gets to the starting blocks he turns around and flips the bird to his father. That's not a euphemism, that's just what he does.

They're off with Scott in lane 5, Condorelli is out like a shot but it's the Brazilian Chierighini at the turn to the delight of the crowd.

Aussie Kyle Chalmers comes back strongly down the second 50m to take first, Condorelli in second and the Belgian Timmers in third.
